Escher Tessellation 104

This tessellation has both translational and rotational symmetry. The centers of rotation are about each lizard's nose, right front foot, right knee, and left rear foot. Each lizard's nose is a center of 2-fold rotation. Ignoring color differences, its right front foot and left rear foot are centers of 4-fold rotation. Each point marks a location at which more than two lizards meet. Joining the points on the same reptile in cyclic order will outline a square.
